Genes affected

ADAP1 (HGNC:16486): (ArfGAP with dual PH domains 1) Enables GTPase activator activity. Involved in regulation of GTPase activity. Located in cytosol; nucleus; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

COX19 (HGNC:28074): (cytochrome c oxidase assembly factor COX19) COX19 encodes a cytochrome c oxidase (COX)-assembly protein. The S. cerevisiae Cox19 protein may play a role in metal transport to the mitochondrial intermembrane space and assembly of complex IV of the mitochondrial respiratory chain (Sacconi et al., 2005 [PubMed 16212937]).[supplied by OMIM, Mar 2008]

ADAP1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.26378417).

The c.429C>G (p.N143K) alteration is located in exon 5 (coding exon 5) of the ADAP1 gene. This alteration results from a C to G substitution at nucleotide position 429, causing the asparagine (N) at amino acid position 143 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
